Created attachment 322247 [details] Ouput of "pulseaudio -vvvv" I get sound skipping or "hickup" issues when playing audio through pulseaudio. Playing using alsa directly works fine. Attached is the output of "pulseaudio -vvvv". The skipping always occurs when a line "I: module-alsa-sink.c: Underrun!" appears.
I confirm having this problem but I'm not sure if it's specific to pulse or alsa because I hear the skips in both alsasink and pulsesink (less frequent) gst-launch filesrc location=test.ogg ! decodebin ! queue ! alsasink gst-launch filesrc location=test.ogg ! decodebin ! queue ! pulsesink but oss4sink or osssink does not work at all gst-launch filesrc location=test.ogg ! decodebin ! queue ! osssink Setting pipeline to PAUSED ... Pipeline is PREROLLING ... ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc0: Internal data flow error. Additional debug info: gstbasesrc.c(2234): gst_base_src_loop (): /GstPipeline:pipeline0/GstFileSrc:filesrc0: streaming task paused, reason not-linked (-1) ERROR: pipeline doesn't want to preroll. Setting pipeline to NULL ... FREEING pipeline ... Caught SIGSEGV accessing address 0x40
Chances are your use of the GStreamer alsasink: > gst-launch filesrc location=test.ogg ! decodebin ! queue ! alsasink also uses PulseAudio (through the PulseAudio ALSA plugin).
